Madonna is facing legal action from the family of adopted daughter Mercy.
The family claim they have not seen Mercy since her adoption in 2009.
The relatives of the five-year-old say the singer broke a promise to allow them regular access, reports The Sun.
Emmie Chanika, a representiative for Malawi's leading civil rights organisation CILIC, said: 'Mercy's family have met me several times over the past year and they have been very upset.
'They have a strong recollection of being told that they would be able to see Mercy and have regular contact with her- and that when she is an adult she will return to live with them in Malawi.
'I believe they have a case in law because there appears to have been a verbal contract between them and Madonna's representatives.'
The singer has also been criticised by the Malawian government after backing out of plans to build a £9 million academy for girls in the country.
